CRASSULA, Linn., sect. TILLAEOIDEAE, Schonl. 
Western Europe it has usually 3-merous flowers, while our plant has 
5-merous flowers. This difference, however, is not of much con- 
sequence as in Europe 4-merous flowers occur wild (I have seen 
them in specimens collected near Paris) and according to De Candolle 
5-merous flowers are found in cultivated specimens. But there is 
a more serious objection to uniting the two species. In the accounts 
of the European plant at my disposal there is no mention of any 
“ squamae,” and I have not been able to find any in some specimens 
I dissected. De Candolle says “ squamae nullae sed forsan minimae 
et oculos effugientes.” Now, I feel very reluctant to unite under one 
species specimens with and without such characteristic organs. But 
even if they are to be united, the question arises, when once they are 
placed under Crassula, whether the name Cr. muscosa (L.), Roth is 
applicable. Linnaeus himself has described a Cr. muscosa in Amoen. 
acad. 6 and PI. Afr. Rar. 10. I have no access at present to the 
original description. Willdenow in Sp. PL I, 1557, gives a short 
notice of it. According to him the plant is an annual and comes from 
“ Ethiopia.” He may have meant our plant (or a nearly allied one), 
but he also mentions the short description of Thunberg (Prodr. 54), 
and if we carefully examine the minute description which is found in 
Thunberg’s Flora Capensis (ed. Schultes) we find that this refers 
to quite a different plant, namely Cr. lycopodioides, Lam. Harvey 
evidently was of opinion that Thunberg mixed up the latter and the 
plant he himself took to be Crassula muscosa, L. However, what 
I have said is sufficient to justify my action in not hurriedly adopting 
Linnaeus’ name.

floral structure appears to be different.
